autotrophs that capture energy and use it to make organic molecules (they manufacture their own food)

when bacteria uses energy stored in organic molecules to produce carbohydrates

gross primary productivity

the rate at which producers in an ecosystem capture the energy of sunlight by producing organic compounds

ecologists refer to the organic material that has been produced in an ecosystem as this

ecologists often measure the rate at which biomass accumulates

they obtain energy by comsuming organic molecules made by other organisms

eat both producers and consumers

consumers that feed on the "garbage" of an ecosystem

detrivores that cause decay by breaking down complex molecules into simpler molecules

indicates the organism's position in a sequence of energy transfers

a single pathway of feeding relationships among organisms in an ecosystem that results in energy transfer

the interrelated food chains in an ecosystem
